A contractor coming out to repair a central AC system in Gibson County has to settle one question before they can quote the job accurately: whether what failed did so from ordinary wear or from the load this area puts on equipment every season. 127 severe weather events were recorded in Gibson County, Indiana between 2015 and 2024. At that rate, severe weather is a standing feature of operating here, and components that absorb the brunt of it, including capacitors, contactors, and condenser hardware, move to the front of any diagnostic. Age still matters, and so does how the system was installed and maintained. But in Gibson County, a contractor who skips the weather-load assessment before pricing a repair is skipping the part of the job that decides which fix actually holds.
Ductwork and wiring aside, what shapes a central AC repair in this county is whether the components a given system requires are still in production. Half the homes in Gibson County, Indiana were built in 1974 or earlier (2020-2024 ACS 5-year). Equipment installed decades after these houses were framed can itself be old enough that certain capacitors, contactors, or control boards are no longer stocked by distributors. A contractor opening a unit here has to verify parts availability before a repair scope makes sense, because a job that looks straightforward can stall on a discontinued component.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it is where heat gets released to the outside air. The compressor lives inside that cabinet and is one of the first things a contractor will inspect when a system stops cooling, because a failed compressor is a common reason a central AC runs but produces no cold air from the vents.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which sits above the heat exchanger in the indoor unit and is a frequent source of trouble when airflow drops or the system starts freezing up. The refrigerant line set runs between the two units, and the contractor will also check the capacitors and contactors in both cabinets, since those smaller electrical components fail more often than the larger parts around them.
The drawing shows a typical central AC layout, and a licensed contractor will determine which components apply to your specific system and situation.

What the Repair Visit Looks Like
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
